It is [Kr] 4d2 5s2
The correct noble gas configuration for Li is neon (1s^2 2s^1).
No, potassium does not have a noble gas electron configuration. The noble gas configuration for potassium would be [Ar] 4s¹, but instead, potassium has the electron configuration 1s² 2s² 2p^6 3s² 3p^6 4s¹.
The noble gas that has the same electron configuration as the oxygen atom in a water molecule is neon (Ne). Both have a full valence shell with 8 electrons, making them stable and unreactive.
Zirconium tetrachloride is obtained by the chlorination of zirconium dioxide (not zirconium carbide).
An atom with 8 electrons in its outer shell is stable and is considered to have a full valence shell. This configuration is known as the octet rule, which means the atom is unlikely to form chemical bonds with other atoms as it is already in a stable state.
The symbol for the noble gas used to represent the core electrons of zirconium is [Kr] (krypton). This notation indicates that the core electrons of zirconium are equivalent to the electron configuration of krypton, which is a noble gas with a filled electron shell, so Zr would have the same core electron configuration as Kr.
The electron configuration of zirconium is: [Kr]5s24d2
The electron configuration of americium is [Rn]5f7.7s2.
[Xe] 4f3 6s2
I assume you mean the Nobel gas electron configuration abbreviation for barium.[Ne] 6s2=======
[Kr] 5s2 4d2
The correct noble gas configuration for Li is neon (1s^2 2s^1).
[Xe] 4f3 6s2
If you think to the electron configuration of promethium this begin with [Xe].
No, potassium does not have a noble gas electron configuration. The noble gas configuration for potassium would be [Ar] 4s¹, but instead, potassium has the electron configuration 1s² 2s² 2p^6 3s² 3p^6 4s¹.
The neutral atom with the electron configuration ( \text{Kr} , 5s^2 , 4d^2 ) is zirconium (Zr). Zirconium has an atomic number of 40, indicating it has 40 electrons. The electron configuration reflects the filling of the 5s and 4d subshells after the noble gas krypton (Kr), which corresponds to the atomic number 36.
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
